Energy Transformed: Building Electrification in DE

Heat pumps work in cold climates. Diminished peaks. Winter peaks on electric grid can be mitigated with weatherization and demand response programs. High efficiency. Ground and water source heat pumps function well without much reduction in efficiency in extreme temperatures. Backup often unnecessary. Today's air-source heat pumps work without back-up down to -15°F with cutting edge products heating at -30°F. Where necessary, backup options vary. Electric resistance or existing fossil fuel infrastructure can be used for backup heating – some heat pump programs leave existing fossil fuel infrastructure as back up source of heating, but electric resistance heating is also effective.
